Just upgraded to enterprise PDM and see the same annoyances.
when browsing through the vault via windows explorer, you cant set the folder/document icons to be "extra large". If you navigate outside of the vault then you can. its been this way for quite awhile now.
when I invoke File->Open, from the SW menu, the selection criteria ALWAYS defaults to part even though I always change it to "all solidworks files".
why is it that such expensive software cant get such a simple thing right when cheap/free software can?
